Doing Self-Study, Plz Have a Look and Suggest books..!

For Tax refer Singhania, For costing and fm refer PC Tulsian, which is specially for students of self-study, for accounts- PC Tulsian or Hanif Mukherjee, for ITSM- Inst. material is sufficient. You can download the latest study materials from below link, it also includes Q&A format. Try to take coaching for Taxation as it is a complex subject and needs more time to understand and for accounts if you are already somewhat familiar earlier, then self-study is sufficient. In addition, you MUST refer all compilations of suggested answers, revision test papers posted in icai.org website and refer the student journal if you have time. Problems given in institute material for above subjects are also to be done compulsorily. All the best.
